OVERVIEW This section contains specific information pertaining to the installation of the Model 3051 Transmitter with FOUNDATION fieldbus.

SAFETY MESSAGES Instructions and procedures in this section may require special precautions to ensure the safety of the personnel performing the operations. Information that raises potential safety issues is indicated by a warning symbol ( ). Please refer to the following safety messages before performing an operation preceded by this symbol.

Warnings

Explosions can result in death or serious injury.

• Do not remove the transmitter covers in explosive environments when thecircuit is alive.

• Both transmitter covers must be fully engaged to meetexplosionproof requirements.

• Verify that the operating atmosphere of the transmitter is consistent with theappropriate hazardous locations certifications.

Electrical shock can result in death or serious injury.

• Avoid contact with the leads and terminals.

Process leaks could result in death or serious injury.

• Install and tighten all four flange bolts before applying pressure.

• Do not attempt to loosen or remove flange bolts while the transmitter isin service.

Replacement equipment or spare parts not approved by Rosemount Inc. for useas spare parts could reduce the pressure retaining capabilities of the transmitterand may render the instrument dangerous.

• Use only bolts supplied with the Model 3051 or sold by Rosemount Inc. asspare parts for the Model 3051.

GENERALCONSIDERATIONS

Measurement accuracy depends upon proper installation of the transmitter and impulse piping. Mount the transmitter close to the process and use a minimum of piping to achieve best accuracy. Keep in mind the need for easy access, personnel safety, practical field calibration, and a suitable transmitter environment. Install the transmitter to minimize vibration, shock, and temperature fluctuation.

IMPORTANTInstall the enclosed pipe plug in unused conduit openings with a minimum of five threads engaged to comply with explosionproof requirements. The transmitter is shipped with the plug installed on transmitters ordered with CSA explosionproof approval.

MECHANICALCONSIDERATIONS

Figures 2-1 through 2-5 on pages 2-3 through 2-6 show dimensional drawings of Model 3051 transmitters. Figure 2-7 on page 2-9 shows installation examples. Figures 2-8 through 2-11 on pages 2-12 through 2-14 show dimensional drawings of mounting brackets.

NOTEFor Model 3051CD0 and 3051CD1, mount the transmitter solidly to prevent tilting. A tilt in the physical transmitter may cause a zero shift in the transmitter output.

NOTEFor steam service, do not blow down impulse piping through the transmitter. Flush the lines with the blocking valves closed and refill the lines with water before resuming measurement.

NOTEWhen the transmitter is mounted on its side, position the Coplanar flange to ensure proper venting or draining. Mount the flange as shown in Figure 2-7 on page 2-9, keeping drain/vent connections on the bottom for gas service and on the top for liquid service.

NOTEThe Model 3051 transmitter incorporates two independent seals between the process connection and the conduit connection.

Figure 2-6. Typical Mounting Configurations for Model 3051 Transmitters with Model 305 and 305 Manifolds.

Mounting The Model 3051C Pressure Transmitter weighs 5.8 lbs (2,6 kg) without additional options. Optional mounting brackets available with the Model 3051 allow mounting to a panel, wall, or 2-inch pipe. The B4 Bracket Option for use with the Coplanar flange and the Model 3051T is 316 SST with 316 SST bolts. Figures 2-8 and 2-9 on pages 2-12 and 2-13 show bracket dimensions and mounting configurations for theB4 Option.

Bracket options B1, B2, B3, B7, B8, and B9 are sturdy polyurethane painted carbon steel brackets designed for use in pipe or panel mounting the traditional flange (H2, H3, H4, or H7 option). The B1–B3 brackets have carbon steel bolts, while the B7–B9 brackets have stainless steel bolts. Bracket options BA and BC are stainless steel with stainless steel bolts. Dimensionally, these brackets are identical to the B1–B3 brackets used with the Rosemount Model 1151 Pressure Transmitter except for the length of the bolts used to mount the transmitter to the bracket. When installing the transmitter to one of the mounting brackets, torque the bolts to 125 inch-pounds.

NOTEThe transmitter is calibrated in an upright position at the factory. If you mount the transmitter in any other position, the zero point will shift by an amount equivalent to the liquid head caused by the varied mounting position. Execute a zero sensor trim to compensate for mounting position effects, see page D-2.

Mounting Requirements Refer to Figure 2-7 for examples of the following mounting configurations:

Liquid Flow Measurement

• Place taps to the side of the line to prevent sediment deposits on the transmitter’s process isolators.

• Mount the transmitter beside or below the taps so gases can vent into the process line.

• Mount drain/vent valve upward to allow gases to vent.

Gas Flow Measurement

• Place taps in the top or side of the line.

• Mount the transmitter beside or above the taps so liquid will drain into the process line.

Steam Flow Measurement

• Place taps to the side of the line.

• Mount the transmitter below the taps to ensure that the impulse piping will stay filled with condensate.

• Fill impulse lines with water to prevent the steam from contacting the transmitter directly and to ensure accurate measurement at start-up.

NOTEIn steam or other elevated temperature services, it is important that temperatures at the coplanar process flanges not exceed 250 °F (121 °C) for transmitters with silicone fill or 185 °F (85 °C) for inert fill. In vacuum service, these temperature limits are reduced to 220 °F (104 °C) for silicone fill and 160 °F (71 °C) for inert fill. Models 3051L, and the traditional flange allow higher temperatures.

2-9

Installation

Figure 2-7. Installation Examples.

Impulse Piping The piping between the process and the transmitter must accurately transfer the pressure to obtain accurate measurements. There are five possible sources of error: pressure transfer, leaks, friction loss (particularly if purging is used), trapped gas in a liquid line, liquid in a gas line, and density variations between the legs.

The best location for the transmitter in relation to the process pipe depends on the process itself. Use the following guidelines to determine transmitter location and placement of impulse piping:

• Keep impulse piping as short as possible.

• For liquid service, slope the impulse piping at least 1 inch per foot (8 cm per m) upward from the transmitter toward the process connection.

• For gas service, slope the impulse piping at least 1 inch per foot (8 cm per m) downward from the transmitter toward the process connection.

• Avoid high points in liquid lines and low points in gas lines.

• Make sure both impulse legs are the same temperature.

• Use impulse piping large enough to avoid friction effects and blockage.

• Vent all gas from liquid piping legs.

• When measuring a fluid, fill both piping legs to the same level.

• When purging, make the purge connection close to the process taps and purge through equal lengths of the same size pipe. Avoid purging through the transmitter.

• Keep corrosive or hot (above 250 °F [121 °C]) process material out of direct contact with the sensor module and flanges.

• Prevent sediment deposits in the impulse piping.

• Keep the liquid head balanced on both legs of the impulse piping.

• Avoid conditions that might allow process fluid to freeze within the process flange.

Process Connections Model 3051 process connections on the transmitter flange are 1/4-18 NPT. Flange adapter unions with 1/2–14 NPT connections are supplied as standard. The threads are Class 2; use your plant-approved lubricant or sealant when making the process connections. The process connections on the transmitter flange are on 21/8-inch (54 mm) centers to allow direct mounting to a three-valve or five-valve manifold. Rotate one or both of the flange adapters to attain connection centers of 2 inches (51 mm), 21/8 inches (54 mm), or 21/4 inches (57 mm). See page 2-10 for information on the Model 3051T process connection.

Install and tighten all four flange bolts before applying pressure, or process leakage will result. When properly installed, the flange bolts will protrude through the top of the module housing. Do not attempt to loosen or remove the flange bolts while the transmitter is in service.

To install adapters to a Coplanar flange, perform the following procedure:

1. Remove the flange bolts.

2. Leaving the flange in place, move the adapters into position with the O-ring installed.

3. Clamp the adapters and the Coplanar flange to the transmitter module using the larger of the bolts supplied.

4. Tighten the bolts. Refer to “Mounting Bolts” on page 2-15 for torque specifications.

See “Safety Messages” on page 2-1 for complete warning information.

Failure to install proper flange adapter O-rings can cause process leaks, which canresult in death or serious injury.

Each style of Rosemount flange adapters requires a unique O-ring, as shown below.Flange adapters are distinguished by their unique grooves.

Use only the O-ring designed to seal with an adapter. Refer to the Spare Parts list inSection 6: Specifications and Reference Data for the correct part numbers of the flangeadapters and O-rings designed for Model 3051 transmitters.

Installation

When compressed, Teflon® O-rings tend to cold flow, which aids in their sealing capabilities. Whenever you remove flanges or adapters, visually inspect the Teflon O-rings. Replace them if there are any signs of damage, such as nicks or cuts. If they are undamaged, you may reuse them. If you replace the O-rings, retorque the flange bolts after installation to compensate for cold flow. Refer to the process sensor body reassembly procedure in Section 7: Maintenance.

Model 3051T ProcessConnection

Housing Rotation The electronics housing can be rotated up to 180 degrees (left or right) to improve field access or to better view the optional LCD meter. To rotate the housing, perform the following procedure:

1. Loosen the housing rotation set screw using a 9/64-in. hex wrench.

NOTEDo not rotate the housing more than 180 degrees without first performing a disassembly procedure (see “Disassembly Procedures” on page 7-2). Over-rotation will sever the electrical connection between the sensor module and the electronics module.

2. Turn the housing up to 180 degrees to the left or right of its original (as shipped) position.

3. Retighten the housing rotation set screw.

Do not apply torque directly to the sensor module. Rotation between the sensor moduleand the process connection can damage the electronics. To avoid damage, apply torqueonly to the hex-shaped process connection.

Model 305 Installation Procedure To install a Model 305 Integral mainfold to a Model 3051 transmitter follow the procedure below.

1. Inspect the Teflon (PTFE) sensor module O-rings. If the O-rings are undamaged, reusing them is recommended. If the O-rings have nicks, cuts, or other damage, replace them with new O-rings.

IMPORTANTDo not scratch or deface the O-ring grooves or the surface of the isolating diaphragm while you remove the O-rings.

2. Install the integral manifold on the sensor module:

a. Align the manifold and sensor module by inserting and finger-tightening the four 2.25-inch (57 mm) manifold bolts.

b. Tighten the bolts incrementally in a cross-pattern until each of them reaches the initial torque value (See Table 2-2, depending upon the bolt material).

c. Tighten the bolts incrementally again until each of them reaches the final torque value (See Table 2-2, depending upon the bolt material).

3. If the Teflon (PTFE) sensor module O-rings have been replaced, the flange bolts should be re-tightened after installation to compensate for cold flow of the O-rings.

4. Install the drain/vent valves:

a. Apply two complete turns of sealing tape to the valve body threads (with the open end of the threads pointing toward you, wrap the tape clockwise beginning at the edge closest to you).

b. Tighten the the valve body into the manifold to 250 in-lb (28,3 N-m).

c. Orient the opening of the valve so that once the transmitter is installed the valve opening will point to the ground and away from personnel when the valve is opened.

d. Tighten the valve bonnet and stem onto the valve body to 70 ± 10 in-lb (7,9 ± 1,1 N-m).

e. Repeat a-d for each drain/vent valve.

NOTEPerform a zero trim on the transmitter/manifold assembly after you combine them to eliminate any mounting effects.

Model 306 IntegralManifolds

The Model 306 integral manifold is for use only with a Model 3051T transmitter.

Model 306 Installation To install a Model 306 Integral mainfold to a Model 3051 transmitter follow the procedure below.

1. Apply two complete turns of sealing tape to the manifold threads (with the open end of the threads pointing toward you, wrap the tape clockwise beginning at the edge closest to you).

2. Turn the manfiold threads into the sensor module to leak tight.

TaggingCommissioning (Paper) Tag When commissioning more than one device on a fieldbus segment, it

can be difficult to identify which device is at a particular location. A removable tag provided with the transmitter can aid in this process by linking the Device ID and a physical location. TheDevice ID is a unique code that identifies a particular device in the absence of a device tag. The device tag is used by the customer as an operational identification for the device and is usually defined by the Piping and Instrumentation Diagram (P & ID).

The installer should note the physical location in both places on the removable commissioning tag and tear off the bottom portion. This should be done for each device on the segment. The bottom portion of the tags can be used for commissioning the segment in the control system, providing a direct link between the Device ID and the tag location.

ELECTRICALCONSIDERATIONS

Proper electrical installation is necessary to prevent errors due to grounding and electrical noise. Shielded, twisted pair cable should be used for best results in electrically noisy environments.

Power Supply The transmitter requires between 9 and 32 V dc to operate and provide complete functionality. The dc power supply should provide power with less than 2% ripple.

Power Conditioner A fieldbus segment requires a power conditioner to isolate the power supply filter and decouple the segment from other segments attached to the same power supply.

Field Wiring All power to the transmitter is supplied over the signal wiring. Signal wiring should be shielded, twisted pair for best results. Do not run unshielded signal wiring in conduit or open trays with power wiring or near heavy electrical equipment. Do not remove the transmitter cover in explosive atmospheres when the circuit is alive.

NOTEDo not apply high voltage (e.g. ac line voltage) to the transmitter terminals. Abnormally high voltage can damage the unit. (Transmitter power terminals are rated to 32 V dc.)

Hazardous Locations The Model 3051 has an explosionproof housing and circuitry suitable for intrinsically safe and non-incendive operation. Individual transmitters are clearly marked with a tag indicating the certifications they carry. See Section 6 Specifications and Reference Data for specific approval categories, and see Section 8 Approval Drawings for installation drawings.

NOTEOnce a device labeled with multiple approval types is installed, it should not be reinstalled using any of the other labeled approval types. To ensure this, the approval label should be permanently marked to distinguish the used from the unused approval type(s).

Power Connections Use ordinary copper wire of sufficient size to ensure that the voltage across the transmitter power terminals does not go below 9 V dc. To power the transmitter, connect the power leads to the terminals marked “FIELDBUS WIRING” as shown in Figure 2-17. The power terminals are polarity insensitive, which means the electrical polarity of the power leads does not matter when connecting to the power terminals. When wiring to screw terminals, the use of crimped lugs is recommended. Tighten the terminal screws to ensure adequate contact.

Grounding Neither conductor of the fieldbus segment can be grounded. Grounding out one of the signal wires will shut down the entire fieldbus segment.

Shielded Wire Recommended grounding techniques for shielded wire usually call for a single grounding point for each shielded wire to avoid creating a ground loop. The ground point is typically at the power supply.

Grounding theTransmitter Housing

The transmitter housing should always be grounded in accordance with national and local electrical codes. The most effective transmitter case grounding method is direct connection to earth ground with minimal impedance. Methods for grounding the transmitter case include:

• Internal Ground Connection: The Internal Ground Connection screw is inside the FIELD TERMINALS side of the electronics housing. This screw is identified by a ground symbol ( ), and is standard on all Model 3051 transmitters.

• External Ground Assembly: This assembly is included with the optional transient protection terminal block (Option Code T1), and it is included with CESI/CENELEC Flameproof Certification (Option Code E8), BASEEFA/CENELEC Intrinsic Safety Certification (Option Code I1), and BASEEFA/CENELEC Type N Certification (Option Code N1). The External Ground Assembly can also be ordered with the transmitter (Option Code V5), or as a spare part (03031-0398-0001).

NOTEGrounding the transmitter case using the threaded conduit connection may not provide a sufficient ground. The transient protection terminal block (Option Code T1) does not provide transient protection unless the transmitter case is properly grounded. Use the above guidelines to ground the transmitter case. Do not run the transient protection ground wire with signal wiring as the ground wire may carry excessive current if a lightning strike occurs.

Surges/Transients The transmitter will withstand electrical transients of the energy level usually encountered in static discharges or induced switching transients. However, high-energy transients, such as those induced in wiring from nearby lightning strikes, can damage the transmitter.

Optional TransientProtection Terminal Block

The transient protection terminal block can be ordered as an installed option (Option Code T1 in the transmitter model number) or as a spare part to retrofit existing Model 3051 transmitters in the field. The spare part number is 03031-0332-2002. The symbol shown in Figure 2-18 identifies the transient protection terminal block.

NOTEThe fieldbus physical layer specification requires transmitter communication during extreme operating conditions of 250 Vrms common mode signal. The transient terminal block was designed to limit common mode voltages to 90 V and cannot be used in these extreme operating conditions.

2-25

Installation

Figure 2-18. Transient ProtectionTerminal Block.

Installation When the transient protection terminal block is ordered as a spare part, it must be installed in place of the standard terminal block inside the transmitter housing. See “Remove the Terminal Block” on page 7-2.

NOTEThe transient protection terminal block provides transient protection only if the transmitter housing is properly grounded. See “Grounding the Transmitter Housing” on page 2-24.

Performance The transient protection terminal block increases the ability of the Model 3051 transmitter to withstand electrical transients induced by lightning, welding, or heavy electrical equipment. With the transient protection block installed, the Model 3051 transmitter meets the standard performance specifications as outlined in this product manual. In addition, the transient protection circuitry meets IEEE Standard 587, Category B and IEEE Standard 472, Surge Withstand Capability.

Jumpers

Security After you configure the transmitter, you may want to protect the configuration data from unwarranted changes. Each transmitter is equipped with a security jumper that can be positioned “ON” to prevent the accidental or deliberate change of configuration data. The jumper is located on the front side of the electronics module and is labeled SECURITY (see Figure 2-19).

Simulate The simulate jumper is used in conjunction with the Analog Input (AI) function block. This switch is used to simulate the measurement and is used as a lock-out feature for the AI function block. To enable the simulate feature, insert the jumper across “ENABLE” (see Figure 2-19) while the transmitter is powered.

NOTEWhen power is cycled to the transmitter, simulate is automatically disabled regardless of the position of the jumper. This prevents the transmitter from being accidentally left in simulate mode. Therefore, to enable the simulate feature, the jumper must be inserted after power is applied to the transmitter.

ENVIRONMENTALCONSIDERATIONS

The Model 3051 can tolerate a wide range of applications. To optimize performance, mount the transmitter to minimize ambient temperature changes, to avoid vibration and mechanical shock, and to avoid external contact with corrosive materials. Section 6: Specifications and Reference Data lists the transmitter temperature operating limits.

Access Requirements When choosing an installation location and position, take into account the need for access to the transmitter.

Process Flange Orientation Mount the process flanges with sufficient clearance for process connections. For safety reasons, place the drain/vent valves so the process fluid is directed away from technicians when the vents are used. In addition, consider the possible need for a testing or calibration input.

Housing Rotation See “Housing Rotation” on page 2-11.

Terminal Side ofElectronics Housing

Mount the transmitter so that the terminal side is accessible. A 0.75-inch (19 mm) clearance is required for cover removal. Install the provided conduit plug on the unused side of the conduit opening.

Circuit Side ofElectronics Housing

Provide 3 inches (76.2 mm) clearance for cover removal. Three inches of clearance is required for cover removal if a meter is installed.

Cover Installation Always install the electronics housing covers metal-to-metal to ensure a proper seal.

3 Operation

INTRODUCTION This section covers basic operation, software functionality, and basic configuration procedures for the Model 3051 transmitter with FOUNDATION fieldbus (Device Revision 3(1)). For more information about the FOUNDATION™ fieldbus technology and the function blocks used in the Model 3051 transmitter, refer to Sections 4 and 5, and Appendices A–C.

Figure 3-1 illustrates how the pressure signal is channelled through the transmitter.

Figure 3-1. Function Block Diagram for the Model 3051 Transmitter with FOUNDATION fieldbus.

Overview Each FOUNDATION fieldbus configuration tool or host device has a different way of displaying and performing configurations. Some will use Device Descriptions (DD) and DD Methods to make configuration and displaying of data consistent across host platforms. Since there is no requirement that a configuration tool or host support these features, this section will describe how to reconfigure the device manually. Appendix D: Operation with Fisher-Rosemount® DeltaV™ shows the Delta V implementation of these common functions.

Assigning Device Tag andNode Address

The transmitter is shipped with a blank tag and a temporary address (unless specifically ordered with both) to allow a host to automatically assign an address and a tag. If the tag or address needs to be changed, use the features of the configuration tool. The tools basically do the following:

1. Change tag to new value.(1)

2. Change address to new address.

When the device is at a temporary address, only the tag and address can be changed or written to. The resource, transducer, and function blocks are all disabled.

Pressure Specific BlockConfiguration

AI Block NOTEAs a general convention, parameters within blocks are referred to in the following manner: <block ID> .<parameter>, where <block ID> is the default name of the block (such as TB for transducer block), and <parameter> is the block parameter (such as CAS_IN).

For example AI1.OUT_D refers to the OUT_D parameter of Analog Input block number 1.

Unless otherwise specified, the block referred to is that of the Model 3051 transmitter rather than a block in another instrument.

The Analog Input (AI) function block provides the primary interface of the measurement to the control and/or monitoring systems. The interface between the AI block and the Transducer Block (TB) is basically through 3 parameters. The CHANNEL parameter defines which transducer block measurement is used by the AI block. The preconfigured values are AI1.CHANNEL = 1 (P) and AI2.CHANNEL = 2 (ST). The second parameter is the XD_SCALE.UNITS_INDEX. The configuration is set at the factory per user calibration units.

Finally, since the measurement from the transducer block is in the correct units, L_TYPE is configured as Direct. Please note the that these parameters must be changed in the following order:

1. Set MODE_BLK.TARGET to OOS

2. CHANNEL

3. XD_SCALE.UNITS_INDEX

4. L_TYPE

5. Set MODE_BLK.TARGET to AUTO

NOTEPlease refer to Appendix B: Analog Input (AI) Function Block for more details on configuring and troubleshooting the AI block.

(1) For your convenience, the transmitter has been supplied with a removable tag to aid inthe commissioning process of multiple devices (see Tagging on page 2-21).

Operation

General BlockConfiguration

In general, only the Transducer (TB) and Analog Input (AI) blocks have configurations for pressure-specific parameters. All other function blocks are configured by linking the AI block to other blocks to be used for control and/or monitoring applications. See the appropriate function block Appendix for specific application examples.

Configuring Links andScheduling BlockExecution

Without configuring the links between blocks and scheduling the blocks to execute in proper order, the application will not work correctly. Most hosts and/or configuration tools make this task a simple matter by using a Graphical User Interface (GUI).

Measurement Application: When using the Model 3051 transmitter, configure the setup and links/schedules according to Figure 3-2.

Transducer Block

Diagnostics In addition to the BLOCK_ERR and XD_ERROR parameters, more detailed information on the measurement status can be obtained via TB_DETAILED_STATUS. Table 4-3 lists the potential errors and the possible corrective actions for the given values. The corrective actions are in order of increasing system level compromises. The first step should always be to reset the transmitter and then if the error persists, try the steps in Table 4-3. Start with the first corrective action and then try the second.

Modes The transducer block supports two modes of operation as defined by the MODE_BLK Parameter:

Automatic (Auto)—The channel outputs reflect the analog input measurement.

Out of Service (OOS)—Channel outputs status is set to Bad: Out of Service for each channel. The BLOCK_ERR parameter shows Out of Service. In this mode, you can make changes to all configurable parameters. The target mode of a block may be restricted to one or more of the supported modes.

Alarm Detection Alarms are not generated by the transducer block. By correctly handling the status of the channel values, the down stream block (AI) will generate the necessary alarms for the measurement. The error that generated this alarm can be determined by looking at BLOCK_ERR and XD_ERROR and TB_DETAILED_STATUS.

Status Handling Normally, the status of the output channels reflects the status of the measurement value, the operating condition of the measurement electronics, and any active alarm condition.

In Auto mode, PRIMARY_VALUE reflects the value and status quality of the output channels.

Methods

Sensor Calibration In order to calibrate the sensor, the following steps are performed by the user calibration method:

1. Set MODE_BLK.TARGET = OOS.

2. Apply desired pressure (low pressure); allow to stabilize. Pressure applied must be between range limits defined in PRIMARY_VALUE_RANGE.

3. Set CAL_POINT_LO to applied pressure.

4. Apply desired pressure (high pressure); allow to stabilize. Pressure applied must be between range limits defined in PRIMARY_VALUE_RANGE and greater than CAL_POINT_LO + CAL_MIN_SPAN.

5. Set CAL_POINT_HI to applied pressure.

6. Set SENSOR_CAL_DATE to current date.

7. Set SENSOR_CAL_WHO to person responsible for calibration.

8. Set SENSOR_CAL_LOC to calibration location.

9. Set MODE_BLK.TARGET = AUTO.

Block Errors Table 5-2 lists conditions reported in the BLOCK_ERR parameter. Conditions in bold type are available. Conditions in italics are inactive for the Resource block and are given here only for your reference.

Diagnostics In addition to the BLOCK_ERR parameters, more detailed information on the device status can be obtained via DETAILED_STATUS. Table 5.3 lists potential errors and possible corrective actions for the given values. The first step should always be to reset the transmitter, then if the error persists, try steps in Table 5.3. Start with the first corrective action, and then try the second.

TEST_RW 08 A parameter for a host to use to test reading and writing. Not used by the device at all.

UPDATE_EVT 35 This alert is generated by any change to the static data.

WRITE_ALM 40 This alert is generated if the write lock parameter is cleared.

WRITE_LOCK 34 If set, no writes from anywhere are allowed, except to clear WRITE_LOCK. Blockinputs will continue to be updated.

Modes The resource block supports two modes of operation as defined by the MODE_BLK parameter:

• Automatic (Auto) The block is processing its normal background memory checks.

• Out of Service (OOS) The block is not processing its tasks. When the resource block is in OOS, all blocks within the resource (device) are forced into OOS. The BLOCK_ERR parameter shows Out of Service. In this mode, you can make changes to all configurable parameters. The target mode of a block may be restricted to one or more of the supported modes.

Alarm Detection A block alarm will be generated whenever the BLOCK_ERR has an error bit set. The types of block error for the resource block are defined above.

A write alarm is generated whenever the WRITE_LOCK parameter is cleared. The priority of the write alarm is set in the WRITE_PRI parameter:

Alarms are grouped into five levels of priority

Status Handling There are no status parameters associated with the resource block.

VCR (VirtualCommunicationsRelationships)

The number of configurable Virtual Communications Relationships (VCRs) is 8. The parameter is not contained or viewable within the resource block, but it does apply to all blocks.

DISASSEMBLYPROCEDURES

Do not remove the instrument cover in explosive atmospheres when the circuit is alive.

Remove the Transmitterfrom Service

NOTEOnce you have determined a transmitter to be inoperable, remove it from service.

Be aware of the following:

• Isolate and vent the process from the transmitter before removing the transmitter from service.

• Remove all electrical leads and conduit. Avoid grounding out the lead wires if other devices on the fieldbus segment are operational.

• Detach the process flange by removing the four flange bolts and the two alignment screws that secure it.

• Do not scratch, puncture, or depress the isolating diaphragms.

• Clean isolating diaphragms with a soft rag and a mild cleaning solution, and rinse with clear water.

• Whenever you remove the process flange or flange adapters, visually inspect the Teflon O-rings. Replace the O-rings if they show any signs of damage, such as nicks or cuts. If they are undamaged, you may reuse them.

The Model 3051C transmitter is attached to the process connection by four bolts and two cap screws. Remove the four bolts and separate the transmitter from the process connection manifold or flange. You can leave the process connection in place and ready for re-installation.

The Model 3051T is attached to the process by a single hex nutprocess connection. Loosen the hex nut to separate the transmitter from the process.

Remove the Terminal Block Electrical connections are located on the terminal block in the compartment labelled “FIELD TERMINALS.”

Loosen the two small screws located at the 9 o'clock and 4 o'clock positions, and pull the entire terminal block out to remove it.

Reassemble the ProcessConnection to theSensor Module

1. Visually inspect the Teflon (PTFE) sensor module O-rings. If the O-rings are undamaged, you may reuse them. If the O-rings show signs of damage, such as nicks or cuts, or if there is any doubt about their ability to seal properly, replace them with new O-rings.

NOTEIf you are replacing the O-rings, be careful not to scratch the O-ring grooves or the surface of the isolating diaphragm when removing the damaged O-rings.

2. Install the process flange on the sensor module. To hold the process flange in place, install the two hex head alignment screws. These screws are not pressure retaining and need only be finger tight. Do not overtighten; this will affect the module/flange alignment.

3. Install the appropriate flange bolts.

a. IF the installation requires a 1/4–18 NPT mounting, THEN use four 1.75-inch flange bolts. Go to Step f.

b. IF the installation requires a 1/2–14 NPT mounting, THEN use four 2.88-inch process flange/adapter bolts. EXCEPTION: For gage pressure configurations, use two 2.88-inch bolts and two 1.75-inch bolts. Go to Step d.

c. IF the installation uses a three-valve manifold (differential pressure applications only), THEN use four 2.25-inch manifold flange bolts. Go to Step e.

d. Hold the flange adapters and adapter O-rings in place while finger-tightening the bolts. Go to Step g.

e. Align the process flange with the three-valve manifold.

f. Finger tighten the bolts.

g. Tighten the bolts to the inital torque value using a crossed pattern. See Table 7-1 for appropriate torque values.

h. Tighten the bolts to the final torque value using a crossed pattern. See Table 7-1 for appropriate torque values. When fully tightened, the bolts should extend through the top of the module housing.

i. If the installation uses a three-valve manifold, then install flange adapters on the process end of the manifold using the 1.75-inch flange bolts supplied with the transmitter.

Maintenance

4. IF you replaced the Teflon sensor module O-rings, THEN re-torque the flange bolts after installation to compensate for cold flow.

5. Install the drain/vent valve.

a. Apply sealing tape to the threads on the seat. Starting at the base of the valve with the threaded end pointing toward the installer, apply two clockwise turns of the sealing tape.

b. Take care to place the vent opening on the valve so that process fluid will drain toward the ground and away from personnel when the valve is opened.

c. Tighten the drain/vent valve to 250 in.-lb (28.25 N-m).

NOTEAfter replacing O-rings on Range 1 transmitters and re-installing the process flange, expose the transmitter to a temperature of 185 °F (85 °C) for two hours. Then re-tighten the flange bolts in a cross pattern, and again expose the transmitter to a temperature of 185 °F (85 °C) for two hours before calibration.

A FOUNDATION™ fieldbusTechnology and FieldbusFunction Blocks

OVERVIEW This section introduces fieldbus systems that are common to all fieldbus devices.

INTRODUCTION A fieldbus system is a distributed system composed of field devices and control and monitoring equipment integrated into the physical environment of a plant or factory. Fieldbus devices work together to provide I/O and control for automated processes and operations. The Fieldbus Foundation provides a framework for describing these systems as a collection of physical devices interconnected by a fieldbus network. One of the ways that the physical devices are used is to perform their portion of the total system operation by implementing one or more function blocks.

Function Blocks Function blocks within the fieldbus device perform the various functions required for process control. Because each system is different, the mix and configuration of functions are different. Therefore, the Fieldbus FOUNDATION has designed a range of function blocks, each addressing a different need.

Function blocks perform process control functions, such as analog input (AI) and analog output (AO) functions as well as proportional-integral-derivative (PID) functions. The standard function blocks provide a common structure for defining function block inputs, outputs, control parameters, events, alarms, and modes, and combining them into a process that can be implemented within a single device or over the fieldbus network. This simplifies the identification of characteristics that are common to function blocks.

The Fieldbus FOUNDATION has established the function blocks by defining a small set of parameters used in all function blocks called universal parameters. The FOUNDATION has also defined a standard set of function block classes, such as input, output, control, and calculation blocks. Each of these classes also has a small set of parameters established for it. They have also published definitions for transducer blocks commonly used with standard function blocks. Examples include temperature, pressure, level, and flow transducer blocks.

The FOUNDATION specifications and definitions allow vendors to add their own parameters by importing and subclassing specified classes. This approach permits extending function block definitions as new requirements are discovered and as technology advances.


A-2

Figure A-1 illustrates the internal structure of a function block. When execution begins, input parameter values from other blocks are snapped-in by the block. The input snap process ensures that these values do not change during the block execution. New values received for these parameters do not affect the snapped values and will not be used by the function block during the current execution.

Figure A-1. Function BlockInternal Structure.

Once the inputs are snapped, the algorithm operates on them, generating outputs as it progresses. Algorithm executions are controlled through the setting of contained parameters. Contained parameters are internal to function blocks and do not appear as normal input and output parameters. However, they may be accessed and modified remotely, as specified by the function block.

Input events may affect the operation of the algorithm. An execution control function regulates the receipt of input events and the generation of output events during execution of the algorithm. Upon completion of the algorithm, the data internal to the block is saved for use in the next execution, and the output data is snapped, releasing it for use by other function blocks.

A block is a tagged logical processing unit. The tag is the name of the block. System management services locate a block by its tag. Thus the service personnel need only know the tag of the block to access or change the appropriate block parameters.

Function blocks are also capable of performing short-term data collection and storage for reviewing their behavior.

Device Descriptions Device Descriptions are specified tool definitions that are associated with the function blocks. Device descriptions provide for the definition and description of the function blocks and their parameters.

To promote consistency of definition and understanding, descriptive information, such as data type and length, is maintained in the device description. Device Descriptions are written using an open language called the Device Description Language (DDL). Parameter transfers between function blocks can be easily verified because all parameters are described using the same language. Once written, the device description can be stored on an external medium, such as a CD-ROM or diskette. Users can then read the device description from the external medium. The use of an open language in the device description permits

interoperability of function blocks within devices from various vendors. Additionally, human interface devices, such as operator consoles and computers, do not have to be programmed specifically for each type of device on the bus. Instead their displays and interactions with devices are driven from the device descriptions.

Device descriptions may also include a set of processing routines called methods. Methods provide a procedure for accessing and manipulating parameters within a device.

BLOCK OPERATION In addition to function blocks, fieldbus devices contain two other block types to support the function blocks. These are the resource block and the transducer block. The resource block contains the hardware specific characteristics associated with a device. Transducer blocks couple the function blocks to local input/output functions.

Instrument-SpecificFunction Blocks

Resource Blocks Resource blocks contain the hardware specific characteristics associated with a device; they have no input or output parameters. The algorithm within a resource block monitors and controls the general operation of the physical device hardware. The execution of this algorithm is dependent on the characteristics of the physical device, as defined by the manufacturer. As a result of this activity, the algorithm may cause the generation of events. There is only one resource block defined for a device. For example, when the mode of a resource block is “out of service,” it impacts all of the other blocks.

Transducer Blocks Transducer blocks connect function blocks to local input/output functions. They read sensor hardware and write to effector (actuator) hardware. This permits the transducer block to execute as frequently as necessary to obtain good data from sensors and ensure proper writes to the actuator without burdening the function blocks that use the data. The transducer block also isolates the function block from the vendor specific characteristics of the physical I/O.

Alerts When an alert occurs, execution control sends an event notification and waits a specified period of time for an acknowledgment to be received. This occurs even if the condition that caused the alert no longer exists. If the acknowledgment is not received within the pre-specified time-out period, the event notification is retransmitted. This assures that alert messages are not lost.

Two types of alerts are defined for the block, events and alarms. Events are used to report a status change when a block leaves a particular state, such as when a parameter crosses a threshold. Alarms not only report a status change when a block leaves a particular state, but also report when it returns back to that state.

NETWORKCOMMUNICATION

Figure A-2 illustrates a simple fieldbus network consisting of a single segment (link).


A-4

Figure A-2. Simple, Single-LinkFieldbus Network.

Link Active Scheduler(LAS)

All links have one and only one Link Active Scheduler (LAS). The LAS operates as the bus arbiter for the link. The LAS does the following:

• recognizes and adds new devices to the link.

• removes non-responsive devices from the link.

• distributes Data Link (DL) and Link Scheduling (LS) time on the link. Data Link Time is a network-wide time periodically distributed by the LAS to synchronize all device clocks on the bus. Link Scheduling time is a link-specific time represented as an offset from Data Link Time. It is used to indicate when the LAS on each link begins and repeats its schedule. It is used by system management to synchronize function block execution with the data transfers scheduled by the LAS.

• polls devices for process loop data at scheduled transmission times.

• distributes a priority-driven token to devices between scheduled transmissions.

Any device on the link may become the LAS, as long as it is capable. The devices that are capable of becoming the LAS are called link master devices. All other devices are referred to as basic devices. When a segment first starts up, or upon failure of the existing LAS, the link master devices on the segment bid to become the LAS. The link master that wins the bid begins operating as the LAS immediately upon completion of the bidding process. Link masters that do not become the LAS act as basic devices. However, the link masters can act as LAS backups by monitoring the link for failure of the LAS and then bidding to become the LAS when a LAS failure is detected.

Only one device can communicate at a time. Permission to communicate on the bus is controlled by a centralized token passed between devices by the LAS. Only the device with the token can communicate. The LAS maintains a list of all devices that need access to the bus. This list is called the “Live List.”

Two types of tokens are used by the LAS. A time-critical token, compel data (CD), is sent by the LAS according to a schedule. A non-time critical token, pass token (PT), is sent by the LAS to each device in ascending numerical order according to address.

Device Addressing Fieldbus uses addresses between 0 and 255. Addresses 0 through 15 are reserved for group addressing and for use by the data link layer. For all Fisher-Rosemount fieldbus devices addresses 20 through 35 are available to the device. If there are two or more devices with the same address, the first device to start will use its programmed address. Each of the other devices will be given one of four temporary addresses between 248 and 251. If a temporary address is not available, the device will be unavailable until a temporary address becomes available.

Scheduled Transfers Information is transferred between devices over the fieldbus using three different types of reporting.

• Publisher/Subscriber: This type of reporting is used to transfer critical process loop data, such as the process variable. The data producers (publishers) post the data in a buffer that is transmitted to the subscriber (S), when the publisher receives the Compel data. The buffer contains only one copy of the data. New data completely overwrites previous data. Updates to published data are transferred simultaneously to all subscribers in a single broadcast. Transfers of this type can be scheduled on a precisely periodic basis.

• Report Distribution: This type of reporting is used to broadcast and multicast event and trend reports. The destination address may be predefined so that all reports are sent to the same address, or it may be provided separately with each report. Transfers of this type are queued. They are delivered to the receivers in the order transmitted, although there may be gaps due to corrupted transfers. These transfers are unscheduled and occur in between scheduled transfers at a given priority.

• Client/Server: This type of reporting is used for request/response exchanges between pairs of devices. Like Report Distribution reporting, the transfers are queued, unscheduled, and prioritized. Queued means the messages are sent and received in the order submitted for transmission, according to their priority, without overwriting previous messages. However, unlike Report Distribution, these transfers are flow controlled and employ a retransmission procedure to recover from corrupted transfers.

Figure A-3 on page -6 diagrams the method of scheduled data transfer. Scheduled data transfers are typically used for the regular cyclic transfer of process loop data between devices on the fieldbus. Scheduled transfers use publisher/subscriber type of reporting for data transfer. The Link Active Scheduler maintains a list of transmit times for all publishers in all devices that need to be cyclically transmitted. When it is time for a device to publish data, the LAS issues a Compel Data (CD) message to the device. Upon receipt of the CD, the device broadcasts or “publishes” the data to all devices on the fieldbus. Any device that is configured to receive the data is called a “subscriber.”


A-6

Figure A-3. Scheduled Data Transfer.

Unscheduled Transfers Figure A-4 diagrams an unscheduled transfer. Unscheduled transfers are used for things like user-initiated changes, including set point changes, mode changes, tuning changes, and upload/download. Unscheduled transfers use either report distribution or client/server type of reporting for transferring data.

All of the devices on the fieldbus are given a chance to send unscheduled messages between transmissions of scheduled data. The LAS grants permission to a device to use the fieldbus by issuing a pass token (PT) message to the device. When the device receives the PT, it is allowed to send messages until it has finished or until the “maximum token hold time” has expired, whichever is the shorter time. The message may be sent to a single destination or to multiple destinations.

Function Block Scheduling Figure A-5 shows an example of a link schedule. A single iteration of the link-wide schedule is called the macrocycle. When the system is configured and the function blocks are linked, a master link-wide schedule is created for the LAS. Each device maintains its portion of the link-wide schedule, known as the Function Block Schedule. The Function Block Schedule indicates when the function blocks for the device are to be executed. The scheduled execution time for each function block is represented as an offset from the beginning of the macrocycle start time.

Figure A-5. Example Link ScheduleShowing scheduled and UnscheduledCommunication.

To support synchronization of schedules, periodically Link Scheduling (LS) time is distributed. The beginning of the macrocycle represents a common starting time for all Function Block schedules on a link and for the LAS link-wide schedule. This permits function block executions and their corresponding data transfers to be synchronized in time.

B Analog Input (AI)Function Block

The Analog Input (AI) function block processes field device measurements and makes them available to other function blocks. The output value from the AI block is in engineering units and contains a status indicating the quality of the measurement. The measuring device may have several measurements or derived values available in different channels. Use the channel number to define the variable that the AI block processes.

The AI block supports alarming, signal scaling, signal filtering, signal status calculation, mode control, and simulation. In Automatic mode, the block’s output parameter (OUT) reflects the process variable (PV) value and status. In Manual mode, OUT may be set manually. The Manual mode is reflected on the output status. A discrete output (OUT_D) is provided to indicate whether a selected alarm condition is active. Alarm detection is based on the OUT value and user specified alarm limits. Figure B-1 on page -3 illustrates the internal components of the AI function block, and Table B-1 lists the AI block parameters and their units of measure, descriptions, and index numbers.

Analog Input (AI) Function Block

Simulation To support testing, you can either change the mode of the block to manual and adjust the output value, or you can enable simulation through the configuration tool and manually enter a value for the measurement value and its status. In both cases, you must first set the ENABLE jumper on the field device.

NOTEAll fieldbus instruments have a simulation jumper. As a safety measure, the jumper has to be reset every time there is a power interruption. This measure is to prevent devices that went through simulation in the staging process from being installed with simulation enabled.

With simulation enabled, the actual measurement value has no impact on the OUT value or the status.

Filtering The filtering feature changes the response time of the device to smooth variations in output readings caused by rapid changes in input. You can adjust the filter time constant (in seconds) using the PV_FTIME parameter. Set the filter time constant to zero to disable the filter feature.

Signal Conversion You can set the signal conversion type with the Linearization Type (L_TYPE) parameter. You can view the converted signal (in percent of XD_SCALE) through the FIELD_VAL parameter.

You can choose from direct, indirect, or indirect square root signal conversion with the L_TYPE parameter.

Direct Direct signal conversion allows the signal to pass through the accessed channel input value (or the simulated value when simulation is enabled).

Indirect Indirect signal conversion converts the signal linearly to the accessed channel input value (or the simulated value when simulation is enabled) from its specified range (XD_SCALE) to the range and units of the PV and OUT parameters (OUT_SCALE).

Indirect Square Root Indirect Square Root signal conversion takes the square root of the value computed with the indirect signal conversion and scales it to the range and units of the PV and OUT parameters.

When the converted input value is below the limit specified by the LOW_CUT parameter, and the Low Cutoff I/O option (IO_OPTS) is enabled (True), a value of zero is used for the converted value (PV). This option is useful to eliminate false readings when the differential pressure measurement is close to zero, and it may also be useful with zero-based measurement devices such as flowmeters.

NOTELow Cutoff is the only I/O option supported by the AI block. You can set the I/O option in Manual or Out of Service mode only.

Block Errors Table B-2 lists conditions reported in the BLOCK_ERR parameter. Conditions in italics are inactive for the AI block and are given here only for your reference.

Modes The AI Function Block supports three modes of operation as defined by the MODE_BLK parameter:

• Manual (Man) The block output (OUT) may be set manually

• Automatic (Auto) OUT reflects the analog input measurement or the simulated value when simulation is enabled.

• Out of Service (O/S) The block is not processed. FIELD_VAL and PV are not updated and the OUT status is set to Bad: Out of Service. The BLOCK_ERR parameter shows Out of Service. In this mode, you can make changes to all configurable parameters. The target mode of a block may be restricted to one or more of the supported modes.

Alarm Detection A block alarm will be generated whenever the BLOCK_ERR has an error bit set. The types of block error for the AI block are defined above.

Process Alarm detection is based on the OUT value. You can configure the alarm limits of the following standard alarms:

• High (HI_LIM)

• High high (HI_HI_LIM)

• Low (LO_LIM)

• Low low (LO_LO_LIM)

In order to avoid alarm chattering when the variable is oscillating around the alarm limit, an alarm hysteresis in percent of the PV span can be set using the ALARM_HYS parameter. The priority of each alarm is set in the following parameters:

• HI_PRI

• HI_HI_PRI

• LO_PRI

• LO_LO_PRI

Alarms are grouped into five levels of priority:

Status Handling Normally, the status of the PV reflects the status of the measurement value, the operating condition of the I/O card, and any active alarm condition. In Auto mode, OUT reflects the value and status quality of the PV. In Man mode, the OUT status constant limit is set to indicate that the value is a constant and the OUT status is Good.

The Uncertain - EU range violation status is always set, and the PV status is set high- or low-limited if the sensor limits for conversion are exceeded.

In the STATUS_OPTS parameter, you can select from the following options to control the status handling:

BAD if Limited – sets the OUT status quality to Bad when the value is higher or lower than the sensor limits.

Uncertain if Limited – sets the OUT status quality to Uncertain when the value is higher or lower than the sensor limits.

Uncertain if in Manual mode – The status of the Output is set to Uncertain when the mode is set to Manual

NOTES1. The instrument must be in Manual or Out of Service mode to set the status option.2. The AI block only supports the BAD if Limited option. Unsupported options are not grayed out; they appear on the screen in the same manner as supported options.

Advanced Features The AI function block provided with Fisher-Rosemount fieldbus devices provides added capability through the addition of the following parameters:

ALARM_TYPE – Allows one or more of the process alarm conditions detected by the AI function block to be used in setting its OUT_D parameter.

PriorityNumber

Priority Description

0 The priority of an alarm condition changes to 0 after the condition that caused thealarm is corrected.

1 An alarm condition with a priority of 1 is recognized by the system, but is notreported to the operator.

2 An alarm condition with a priority of 2 is reported to the operator, but does notrequire operator attention (such as diagnostics and system alerts).

3-7 Alarm conditions of priority 3 to 7 are advisory alarms of increasing priority.8-15 Alarm conditions of priority 8 to 15 are critical alarms of increasing priority.

B-7


OUT_D – Discrete output of the AI function block based on the detection of process alarm condition(s). This parameter may be linked to other function blocks that require a discrete input based on the detected alarm condition.

VAR_SCAN – Time period in seconds over which the variability index (VAR_INDEX) is computed.

VAR_INDEX – Process variability index measured as the integral of average absolute error between PV and its mean value over the previous evaluation period. This index is calculated as a percent of OUT span and is updated at the end of the time period defined by VAR_SCAN.

Application Information The configuration of the AI function block and its associated output channels depends on the specific application. A typical configuration for the AI block involves the following parameters:

CHANNEL If the device supports more than one measurement, verify that the selected channel contains the appropriate measurement or derived value.

L_TYPE Select Direct when the measurement is already in the engineering units that you want for the block output.

Select Indirect when you want to convert the measured variable into another, for example, pressure into level or flow into energy.

Select Indirect Square Root when the block I/O parameter value represents a flow measurement made using differential pressure, and when square root extraction is not performed by the transducer.

SCALING XD_SCALE provides the range and units of the measurement and OUT_SCALE provides the range and engineering units of the output.

Setpoint Selectionand Limiting

The setpoint of the PID block is determined by the mode. You can configure the SP_HI_LIM and SP_LO_LIM parameters to limit the setpoint. In Cascade or RemoteCascade mode, the setpoint is adjusted by another function block or by a host computer, and the output is computed based on the setpoint.

In Automatic mode, the setpoint is entered manually by the operator, and the output is computed based on the setpoint. In Auto mode, you can also adjust the setpoint limit and the setpoint rate of change using the SP_RATE_UP and SP_RATE_DN parameters.

In Manual mode the output is entered manually by the operator, and is independent of the setpoint. In RemoteOutput mode, the output is entered by a host computer, and is independent of the setpoint.

Figure C-2 illustrates the method for setpoint selection.

Filtering The filtering feature changes the response time of the device to smooth variations in output readings caused by rapid changes in input. You can configure the filtering feature with the FILTER_TYPE parameter, and you can adjust the filter time constant (in seconds) using the PV_FTIME or SP_FTIME parameters. Set the filter time constant to zero to disable the filter feature.

Feedforward Calculation The feedforward value (FF_VAL) is scaled (FF_SCALE) to a common range for compatibility with the output scale (OUT_SCALE). A gain value (FF_GAIN) is applied to achieve the total feedforward contribution.

Tracking You enable the use of output tracking through the control options. You can set control options in Manual or Out of Service mode only.

The Track Enable control option must be set to True for the track function to operate. When the Track in Manual control option is set to True, tracking can be activated and maintained only when the block is in Manual mode. When Track in Manual is False, the operator can override the tracking function when the block is in Manual mode. Activating the track function causes the block’s actual mode to revert to Local Override .

The TRK_VAL parameter specifies the value to be converted and tracked into the output when the track function is operating. The TRK_SCALE parameter specifies the range of TRK_VAL.

When the TRK_IN_D parameter is True and the Track Enable control option is True, the TRK_VAL input is converted to the appropriate value and output in units of OUT_SCALE.

Output Selectionand Limiting

Output selection is determined by the mode and the setpoint. In Automatic , Cascade , or RemoteCascade mode, the output is computed by the PID control equation. In Manual and RemoteOutput mode, the output may be entered manually (see also Figure on page C-5). You can limit the output by configuring the OUT_HI_LIM and OUT_LO_LIM parameters.

Bumpless Transfer andSetpoint Tracking

You can configure the method for tracking the setpoint by configuring the following control options (CONTROL_OPTS):

PID Function Block

SP-PV Track in LO or IMan — Permits the SP to track the PV when the actual mode of the block is Local Override (LO) or Initialization Manual (IMan).

When one of these options is set, the SP value is set to the PV value while in the specified mode.

You can select the value that a master controller uses for tracking by configuring the Use PV for BKCAL_OUT control option. The BKCAL_OUT value tracks the PV value. BKCAL_IN on a master controller connected to BKCAL_OUT on the PID block in an open cascade strategy forces its OUT to match BKCAL_IN, thus tracking the PV from the slave PID block into its cascade input connection (CAS_IN). If the Use PV for BKCAL_OUT option is not selected, the working setpoint (SP_WRK) is used for BKCAL_OUT.

You can set control options in Manual or Out of Service mode only. When the mode is set to Auto , the SP will remain at the last value (it will no longer follow the PV.

PID Equation Structures Configure the STRUCTURE parameter to select the PID equation structure. You can select one of the following choices:

• PI Action on Error, D Action on PV

• PID Action on Error

• I Action on Error, PD Action on PV

Set RESET to zero to configure the PID block to perform integral only control regardless of the STRUCTURE parameter selection. When RESET equals zero, the equation reduces to an integrator equation with a gain value applied to the error:

Reverse and Direct Action To configure the block output action, enable the Direct Acting control option. This option defines the relationship between a change in PV and the corresponding change in output. With Direct Acting enabled (True), an increase in PV results in an increase in the output.

You can set control options in Manual or Out of Service mode only.

NOTETrack Enable , Track in Manual , SP-PV Track in Man , SP-PV Track in LOor IMan, Use PV for BKCAL_OUT , and Direct Acting are the only control options supported by the PID function block. Unsupported options are not grayed out; they appear on the screen in the same manner as supported options.

Reset Limiting The PID function block provides a modified version of feedback reset limiting that prevents windup when output or input limits are encountered, and provides the proper behavior in selector applications.

Block Errors Table C-2 lists conditions reported in the BLOCK_ERR parameter. Conditions in italics are inactive for the PID block and are given here only for your reference.

Modes The PID function block supports the following modes:

Manual (Man)—The block output (OUT) may be set manually.

Automatic (Auto)—The SP may be set manually and the block algorithm calculates OUT.

Cascade (Cas)—The SP is calculated in another block and is provided to the PID block through the CAS_IN connection.

RemoteCascade (RCas)—The SP is provided by a host computer that writes to the RCAS_IN parameter.

RemoteOutput (Rout)—The OUT IS provided by a host computer that writes to the ROUT_IN parameter

Local Override (LO)—The track function is active. OUT is set by TRK_VAL. The BLOCK_ERR parameter shows Local override.

Initialization Manual (IMan)—The output path is not complete (for example, the cascade-to-slave path might not be open). In IMan mode, OUT tracks BKCAL_IN.

Out of Service (O/S)—The block is not processed. The OUT status is set to Bad: Out of Service. The BLOCK_ERR parameter shows Out of service.

You can configure the Man, Auto, Cas, and O/S modes as permitted modes for operator entry.

Alarm Detection A block alarm will be generated whenever the BLOCK_ERR has an error bit set. The types of block error for the AI block are defined above.

PID Function Block

Process alarm detection is based on the PV value. You can configure the alarm limits of the following standard alarms:

• High (HI_LIM)

• High high (HI_HI_LIM)

• Low (LO_LIM)

• Low low (LO_LO_LIM)

Additional process alarm detection is based on the difference between SP and PV values and can be configured via the following parameters:

• Deviation high (DV_HI_LIM)

• Deviation low (DV_LO_LIM)

In order to avoid alarm chattering when the variable is oscillating around the alarm limit, an alarm hysteresis in percent of the PV span can be set using the ALARM_HYS parameter. The priority of each alarm is set in the following parameters:

• HI_PRI

• HI_HI_PRI

• LO_PRI

• LO_LO_PRI

• DV_HI_PRI

• DV_LO_PRI

Alarms are grouped into five levels of priority:

Status Handling If the input status on the PID block is Bad, the mode of the block reverts to Manual . In addition, you can select the Target to Manual ifBad IN status option to direct the target mode to revert to manual. You can set the status option in Manual or Out of Service mode only.

NOTETarget to Manual if Bad IN is the only status option supported by the PID function block. Unsupported options are not grayed out; they appear on the screen in the same manner as supported options.

Application Information The PID function block is a powerful, flexible control algorithm that is designed to work in a variety of control strategies. The PID block is configured differently for different applications. The following examples describe the use of the PID block for closed-loop control (basic PID loop), feedforward control, cascade control with master and slave, and complex cascade control with override.

PriorityNumber

Priority Description

0 The priority of an alarm condition changes to 0 after the condition thatcaused the alarm is corrected.

1 An alarm condition with a priority of 1 is recognized by the system, but isnot reported to the operator.

2 An alarm condition with a priority of 2 is reported to the operator, but doesnot require operator attention (such as diagnostics and system alerts).

3-7 Alarm conditions of priority 3 to 7 are advisory alarms of increasing priority.8-15 Alarm conditions of priority 8 to 15 are critical alarms of increasing priority.


C-10

Closed Loop Control To implement basic closed loop control, compute the error difference between the process variable (PV) and setpoint (SP) values and calculate a control output signal using a PID (Proportional Integral Derivative) function block.

The proportional control function responds immediately and directly to a change in the PV or SP. The proportional term GAIN applies a change in the loop output based on the current magnitude of the error multiplied by a gain value.

The integral control function reduces the process error by moving the output in the appropriate direction. The integral term RESET applies a correction based on the magnitude and duration of the error. Set the RESET parameter to zero for integral-only control. To reduce reset action, configure the RESET parameter to be a large value.

The derivative term RATE applies a correction based on the anticipated change in error. Derivative control is typically used in temperature control where large measurement lags exist.

The MODE parameter is a switch that indicates the target and actual mode of operation. Mode selection has a large impact on the operation of the PID block:

• Manual mode allows the operator to set the value of the loop output signal directly.

• Automatic mode allows the operator to select a setpoint for automatic correction of error using the GAIN, RESET, and RATE tuning values.

• Cascade and Remote Cascade modes use a setpoint from another block in a cascaded configuration.

• Remote Out mode is similar to Manual mode except that the block output is supplied by an external program rather than by the operator.

• Initialization Manual is a non-target mode used with cascade configurations while transitioning from manual operation to automatic operation.

• Local Override is a non-target mode that instructs the block to revert to Local Override when the tracking or fail-safe control options are activated.

• Out of Service mode disables the block for maintenance.

Abrupt changes in the quality of the input signal can result in unexpected loop behavior. To prevent the output from changing abruptly and upsetting the process, select the SP-PV Track in Man I/O option. This option automatically sets the loop to Manual if a Bad input status is detected. While in manual mode, the operator can manage control manually until a Good input status is reestablished.

Application Example: Basic PIDBlock for Steam Heater Control

Situation A PID block is used with an AI block and an AO block to control the flow steam used to heat a process fluid in a heat exchanger. Figure C-3 illustrates the process instrumentation diagram.

C-11

PID Function Block

Figure C-3. PID Function Block SteamHeater Control Example.

Solution The PID loop uses TT101 as an input and provides a signal to the analog output TCV101. The BKCAL_OUT of the AO block and the BKCAL_IN of the PID block communicate the status and quality of information being passed between the blocks. The status indication shows that communications is functioning and the I/O is working properly. Figure C-4 illustrates the correct function block configuration.

Figure C-4. PID FunctionBlock Diagram for Steam HeaterControl Example.

Application Example:Feedforward Control

Situation In the previous example, control problems can arise because of a time delay caused by thermal inertia between the two flow streams (TT100 and TT101). Variations in the inlet temperature (TT100) take an excessive amount of time to be sensed in the outlet (TT101). This delay causes the product to be out of the desired temperature range.

Solution Feedforward control is added to improve the response time of the basic PID control. The temperature of the inlet process fluid (TT100) is input to an AI function block and is connected to the FF_VAL connector on the PID block. Feedforward control is then enabled (FF_ENABLE), the feedforward value is scaled (FF_SCALE), and a gain (FF_GAIN) is determined. Figure C-5 illustrates the process instrumentation diagram, and Figure C-6 illustrates the correct function block configuration.

Application Example: CascadeControl with Masterand Slave Loops

Situation A slave loop is added to a basic PID control configuration to measure and control steam flow to the steam heater. Variations in the steam pressure cause the temperature in the heat exchanger to change. The temperature variation will later be sensed by TT101. The temperature controller will modify the valve position to compensate for the steam pressure change. The process is slow and causes variations in the product temperature.

Application Example:Cascade Control with Override

You can use the PID function block with other function blocks for complex control strategies. Figure C-9 illustrates the function block diagram for cascade control with override.

When configured for cascade control with override, if one of the PID function blocks connected to the selector inputs is deselected, that PID block filters the integral value to the selected value (the value at its BKCAL_IN). The selected PID block behaves normally and the deselected controller never winds up. At steady state, the deselected PID block offsets its OUT value from the selected value by the proportional term. When the selected block becomes output-limited, it prevents the integral term from winding further into the limited region.

When the cascade between the slave PID block and the Control Selector block is open, the open cascade status is passed to the Control Selector block and through to the PID blocks supplying input to it. The Control Selector block and the upstream (master) PID blocks have an actual mode of IMan.

If the instrument connected to the AI block fails, you can place the AI block in Manual mode and set the output to some nominal value for use in the Integrator function block. In this case, IN at the slave PID block is constant and prevents the integral term from increasing or decreasing.
